Ureteric stenting after ureteroscopy for removal of distal ureteric stones

To compare patients with stenting and with no stenting after ureteroscopy for distal uretenic calculi. From May 2004 to May 2005, 32 patients complaining of comparable sized small ureteric calculi underwent uncomplicated ureteroscopic retrieval. They were divided into 2 groups, 16 patients in each group [a stented and non stented group]. Average maximum stone diameter was 10 mm. All patients were observed during their hospital stay for occurrence of postoperative hematuria, flank pain, fever or burning micturation. The incidence of hematunia was 12.5% in non stented cases and was 25% in stented cases; the incidence of flank pain was 50% in non stented cases while it was 75% in stented cases. Burning micturation was 50% in non stented cases while it was 100% in stented cases, fever was not encountered in non stented cases but it was encountered in 12.5% of stented cases. The hospital stay in the non stented group ranged from 12-36 hours while it was 24 - 72 hours in the stented group. Uncomplicated ureteroscopy for removing calculi is safe with no stent after treatment. After considering complications and side effects, I think that routine use of ureteric stents after uncomplicated ureteroscopy for stone extraction is unnecessary

Study of prostatic specific antigen versus prostatic biopsy in the diagnosis of prostatic diseases

The majority [60 to 65%] of patients undergoing prostate needle biopsies for abnormal PSA and/or digital rectal examination will not have adenocarcinoma on pathological examination. Benign prostatic hyperplasia [BPH] and prostatitis are causes of PSA elevation. We elected to evaluate the distribution of malignant and non-malignant conditions in patients undergoing prostate needle biopsies. Six hundred and fifty consecutive patients underwent 12 cores Trans rectal Ultrasound [TRUS] guided prostate needle biopsies. None had clinical prostatitis. Prostate volume was measured during the Trus. Pathological examination focused on the presence of normal prostate, BPH, prostatitis and cancer in every core. Patients were stratified into two groups [G] according to digital rectal examination [D. R. E] [G I: Suspicious [+ve DRE], 500 patients or G II: Normal [-ve D.R E], 150 patients. Prostatic volume ranged between 20-135 ml with a median of 43m1. The distribution of cancer, prostatitis, BPH, and abscess on pathology were 177 pts [27%] with a median volume of 36m1, 130 pts [20%] with median volume of 59m;, 307 pts [47.5%] with a median volume of 42ml. and 36 pts [5.5%] with a median volume of 51ml respectively. The majority of pathology on biopsy in patients with suspected prostate cancer is nonmalignant with EPH. Being the most common [47.5%] and prostatitis a significant finding [20%]. Prostatic volume was not a factor in predicting outcome, Except for prostatitis, as expected the higher the PSA, the higher the incidence of prostate cancer
